Becoming increasingly disillusioned with the music business and politically radical, Sky released the controversial and scabrously satirical Songs That Made America Famous in 1973 (the album was recorded in 1971 but rejected by several record companies before it found a home); to this day he claims to have received no royalties for the album. This album featured the earlier known recorded version of the song "Luang Prabang," written by Sky's friend Dave Van Ronk. Patrick Sky had honed his politically charged satire in earlier albums, but Songs That Made America Famous raised the stakes. The Adelphi Records website describes how the content was, indeed, shocking; yet, how several critics encouraged the public to rush to buy these timely and brilliant "explicit lyrics" while it could. Sky gradually moved into the field of Irish traditional music, founding Green Linnet Records in 1973. Today he is recognised as an expert in building and playing the Irish uillean pipes, often performing with his wife, Cathy. He has also published several books on the subject.

In 1995, Sky edited a reissued version of the important 19th-century dance tune book Ryan's Mammonth Collection[1] and followed up in 2001 with a reissue of Howe's 1000 Jigs and Reels.[2]
